The Element: Chlorine

solution of sodium hypochlorite, and dry powder bleaches contain chloride of lime. Since chlorine destroys silk and wool, commercial hypochlorite bleaches should never be used on these fibers. Chlorine is also used as a disinfectant. The oxidizing ability of chloride of lime enables it to destroy bacteria; therefore large amounts are used to treat municipal water systems. This chemical is also used in swimming pools and for treating sewage. Chlorine is used as rock salt. Sodium chloride,...

Metabolism and Enzyme essay

Hydrogen Peroxide and Sodium Hypochlorite Hydrogen peroxide is in bleaches too, but only the mild ones, which is the non-chlorine bleaches. Since only hydrogen peroxide isn’t very strong, other products usually use other chemicals to make the reaction and results more effective, for example; sodium hypochlorite. It is very, very strong. If you’ve experienced accidentally dripping some chlorine bleach on dyed clothes, there would be white spots, which show how strong it is. Sodium hypochlorite uses...

Ammonia Treatment in Textile Processing

pretreatment. Now…. What is Mercerization? Mercerization is a method for processing cellulose fibers by alkalis. This processing makes the inside of the fibers swell to exploit new fiber properties beyond their original feel or physical properties. Sodium hydroxide (NaOH) and ammonia (NH3) are used as the alkaline chemicals for mercerization. Ammonia Mercerizing of cellulose fibers History: The use of ammonia in mercerization has been known since the 1930’s and was developed commercially...

Ground Carbonate Calcium Factory

Ground calcium carbonate, commonly referred to as GCC, is primarily based on limestone and chalk in the UK, though marble stone is imported and processed at a few locations. Generally, the processing includes washing, sorting of undesirable contaminants, grinding, size classification of particles and possibly drying. http://www.crusherindustry.com/index.php/ground-carbonate-calcium-factory-for-sale-uk/ T130x ultrafine grinding mill is a fine powder and ultrafine calcium carbonates powder production...

Electrolysis Lab 13

indicators are usually mixtures of several indicators. The scale for the universal indicator is provided below. Procedure Part A: Universal Indicator and Sodium Sulfate Begin by obtaining a petri dish. Separate the petri dish so you now have two halves in front of you. Pour approximately 5-10 mL of universal indicator to roughly 20-30 mL of sodium sulfate solution. Mix both of them thoroughly. Pour just enough of this solution into the petri dish in order to cover the bottom half of the dish. Obtain...

Descaling a kettle

and washing machines. The chemical name for lime scale is calcium carbonate, chemical formula CaCO3. It is usually caused by hard water (Water containing a higher than normal concentration of dissolved minerals such as calcium and magnesium). http://www.purewaterpeople.co.uk/blog/2013/06/what-is-limescale/ How is lime scale formed? Lime scale is built up over a long period of time. When hard water evaporates the calcium carbonate deposits are left behind and over time they start building up. Lime...
